The invention also relates to a teaching device with such a housing with a connector.

For example, patent document 1 discloses a teaching device for teaching operations to an industrial robot, various actuators, and the like. As shown in fig. 8, a teaching device 1 disclosed in patent document 1 includes a display 3 with a touch panel and a plurality of operation units 4 arranged on a surface of a housing 2 having a substantially rectangular parallelepiped outer shape, and an operator operates the display 3 with the touch panel and the plurality of operation units 4 to teach operations of a controller, not shown, such as a robot and an actuator connected via a cable 5.
In order to improve the operability and convenience of the teaching apparatus 1, a case-side connector 6 is attached to the case 2, a cable-side connector 7 is attached to an end of the cable 5, and the cable 5 is connected to the teaching apparatus 1 by fitting the cable-side connector 7 to the case-side connector 6.

Patent document 1: japanese laid-open patent publication No. 2014-215781
Although the operator grips the housing 2 of the teaching device 1 with both hands and operates the display 3 with a touch panel, and the plurality of operation sections 4 while observing them, it is preferable that the housing-side connector 6 is arranged at a corner portion on the lower side of the housing 2 having a substantially rectangular parallelepiped shape gripped by the operator in some cases so that the cable 5 connected to the housing 2 does not interfere with the operator.
In order to improve the operability and reliability of connection of the cable 5 to the housing 2, the housing-side connector 6 and the cable-side connector 7 used in the teaching apparatus 1 are preferably configured by a so-called one-touch locking type connector assembly that can be easily fitted and locked in a fitted state. As a connector assembly of this one-touch lock type, the following connector assemblies are known: when a plug connector having a coupling nut is fitted to a receptacle connector having a housing, a projection formed on an inner peripheral surface of the coupling nut is fitted to a groove formed on an outer peripheral surface of the housing, thereby locking the fitting of the receptacle connector to the plug connector.
When an operator grips and operates the teaching device 1 in which the cable 5 is connected obliquely to the lower corner of the housing 2 via the housing-side connector 6 and the cable-side connector 7 of the one-touch lock system, if the teaching device 1 is erroneously dropped from the hand of the operator to the right downward direction, the impact of the drop is applied to the housing-side connector 6 and the cable-side connector 7.
Here, in the connector assembly of the one-touch lock type, since the groove portion is formed in the outer peripheral surface of the housing of the receptacle connector, the housing has the thin portion in which the thickness of the housing is reduced in accordance with the formation position of the groove portion. Therefore, if stress is concentrated on the thin portion of the housing when the teaching device 1 is dropped, the housing is damaged, and the connection of the cable 5 by the connector assembly of the one-touch lock system may be damaged.

Fig. 1 shows a teaching device 11 according to an embodiment. The teaching device 11 includes a housing 12 having a substantially rectangular parallelepiped outer shape, and a display 13 and a plurality of operation sections 14 are arranged on a surface of the housing 12. The display 13 may be a display with a touch panel.
Further, a case-side connector 21 (connector) is attached to a corner of the case 12.
A cable-side connector 31 (mating connector) attached to an end of the cable 41 is detachably fitted to the case-side connector 21, and the case-side connector 21 and the cable-side connector 31 constitute a so-called one-touch-lock type connector assembly a.
The housing 12 and the housing-side connector 21 form a housing with a connector, and the teaching device 11 is configured using the housing with a connector.
Here, for convenience of explanation, the surface of the housing 12 on which the display 13 and the plurality of operation portions 14 are arranged extends along the XY plane, and the rectangular parallelepiped forming the outer shape of the housing 12 includes a pair of planes extending along the XY plane and spaced apart in the Z direction perpendicular to the XY plane, a pair of planes extending along the XZ plane and spaced apart in the Y direction, and a pair of planes extending along the YZ plane and spaced apart in the X direction.
The display 13 and the plurality of operation portions 14 are disposed on a plane P1 on the + Z direction side of a pair of planes extending along the XY plane of the housing 12.
The case-side connector 21 is disposed at a corner of the case 12 at an intersection of a plane P2 on the-Y direction side of a pair of planes extending along the XZ plane of the case 12 and a plane P3 on the-X direction side of a pair of planes extending along the YZ plane of the case 12, and is oriented in a direction inclined with respect to these planes P2 and P3.
As shown in fig. 2, the case-side connector 21 has a central axis C1 extending obliquely with respect to a plane P2 extending along the XZ plane of the case 12 and a plane P3 extending along the YZ plane. Specifically, the central axis C1 of the case-side connector 21 is inclined at an angle of 135 degrees with respect to the planes P2 and P3, for example, and extends in a direction from the inside to the outside of the case 12 in parallel with the plane P1 along the XY plane.
The case-side connector 21 is a receptacle connector, and has a plurality of pin contacts 22 extending parallel to the center axis C1, respectively, and an insulator 23 holding the plurality of pin contacts 22. The case-side connector 21 further has: a cylindrical body 24 which is held by the insulator 23, surrounds the plurality of pin contacts 22, and extends in the direction of the center axis C1; and a cylindrical case 25 surrounding the outer peripheries of the insulator 23 and the cylindrical body 24 and extending in the direction of the center axis C1.
An annular gap is formed between the cylinder 24 and the housing 25.
The plurality of pin contacts 22 and the cylindrical body 24 are formed of a conductive material such as metal, and the insulator 23 and the housing 25 are formed of an insulating resin material.
The case 25 has a cylindrical portion 26 exposed to the outside of the case 12 from a corner of the case 12 and extending along the center axis C1, and a pair of groove portions 27 are formed on the outer peripheral surface of the cylindrical portion 26. The pair of grooves 27 are arranged in the Z direction, which is a direction perpendicular to the plane P1 perpendicular to the two planes P2 and P3 forming the corners of the housing 12 as the arrangement position of the housing-side connector 21, with respect to the central axis C1. Specifically, the pair of groove portions 27 is disposed on both sides of the center axis C1 in the Z direction with the center axis C1 interposed therebetween.
The cylindrical portion 26 has a distal end portion 26A as an end portion facing the outside of the housing 12 along the center axis C1. The front end 26A of the cylindrical portion 26 also forms the front end of the housing 25, and the groove portions 27 are open in the front end 26A of the cylindrical portion 26 in a direction along the center axis C1. Further, since the pair of groove portions 27 are formed on the outer peripheral surface of the cylindrical portion 26, the plate thickness of the cylindrical portion 26 at the position where the pair of groove portions 27 are formed is set to be deeper than the plate thickness of the groove portion 27 at the position where the groove portion 27 is not formed, respectively.
A first mark M1 is formed at a predetermined position facing the + Z direction at the corner of the housing 12 where the housing-side connector 21 is disposed. The first mark M1 is a mark indicating a rotational position around the center axis C1 in which the pair of groove portions 27 are formed, and has an arrow shape extending along the center axis C1 toward the outside of the housing 12.
Fig. 3 shows the housing 25 viewed from the + Z direction. The housing 25 has a housing main body 28 integrally connected to the cylindrical portion 26. The housing main body 28 covers the outer peripheral portion of the insulator 23 shown in fig. 2, and is embedded in the housing 12 when the housing-side connector 21 is disposed at the corner of the housing 12.
The groove portion 27 formed on the outer peripheral surface of the cylindrical portion 26 has: a guide portion 27A that opens in a direction along the center axis C1 at the distal end portion 26A of the cylindrical portion 26; and a fixing portion 27B connected to the guide portion 27A. The guide portion 27A has a shape in which the circumferential groove width is narrower from the front end portion 26A of the cylindrical portion 26 toward the rear of the housing 25 along the center axis C1, and the fixing portion 27B is connected to the portion of the guide portion 27A having the narrowest circumferential groove width and extends a predetermined length in the circumferential direction of the cylindrical portion 26.
In addition, any portion of the groove portion 27 having the guide portion 27A and the fixing portion 27B is disposed so as not to intersect a plane P1 which is parallel to both the two planes P2 and P3 orthogonal to the corner portions forming the housing 12 in which the housing-side connector 21 is disposed and which passes through the central axis C1, that is, not to intersect an XY plane which passes through the central axis C1.
Fig. 4 shows a cable-side connector 31, and the cable-side connector 31 is a counterpart connector to the case-side connector 21. The cable-side connector 31 is a plug connector attached to an end of the cable 41, and has a center axis C2 extending on an extension line of the cable 41.
The cable-side connector 31 has a plurality of receptacle contacts 32 extending in parallel with the center axis C2, respectively, and an insulator 33 holding the plurality of receptacle contacts 32. The cable-side connector 31 further includes: a cylindrical body 34 surrounding the outer periphery of the insulator 33 and extending in the direction of the center axis C2; and a cylindrical coupling nut 35 surrounding the outer periphery of the cylindrical body 34 and extending in the direction of the center axis C2.
The plurality of receptacle contacts 32 correspond to the plurality of pin contacts 22 of the case-side connector 21, and an annular gap is formed between the insulator 33 and the cylindrical body 34, and an annular gap is also formed between the cylindrical body 34 and the coupling nut 35.
The plurality of receptacle contacts 32 and the cylindrical body 34 are formed of a conductive material such as metal, and the insulator 33 and the coupling nut 35 are formed of an insulating resin material.
The connection nut 35 is rotatably attached to the cylindrical body 34, and is in a state of applying an elastic force to the cylindrical body 34 in a predetermined rotational direction around the center axis C2 by an unillustrated elastic member incorporated in the cable-side connector 31.
A pair of projections 36 projecting toward the center axis C2 are formed on the inner peripheral surface of the coupling nut 35. The pair of projections 36 are located on one diameter of the coupling nut 35, and are disposed on both sides of the center axis C2 with the center axis C2 interposed therebetween.
Further, a second mark M2 is formed on the outer peripheral surface of the coupling nut 35 corresponding to the arrangement position of the projection 36. The second mark M2 is a mark indicating the arrangement position of the protrusion 36 on the inner peripheral surface of the coupling nut 35, and has an arrow shape extending along the center axis C2 toward the front of the cable-side connector 31 opposite to the side to which the cable 41 is connected.
Further, a strain relief 37 covering the outer periphery of the cable 41 is disposed at the rear of the cable-side connector 31 of the connection cable 41.
Fig. 5 shows a sectional structure of the coupling nut 35 cut by a plane passing through the center axis C2. The projection 36 is formed on the inner peripheral surface of the coupling nut 35 in the vicinity of the front end portion 35A of the coupling nut 35. The projection 36 has a size and a shape that passes through the guide portion 27A of the groove portion 27 of the housing 25 of the case-side connector 21 shown in fig. 3 and is fitted into the fixing portion 27B.
When the cable-side connector 31 having such a configuration is fitted to the case-side connector 21, as shown in fig. 6, the central axis C1 of the case-side connector 21 and the central axis C2 of the cable-side connector 31 constituting the connector assembly a are coaxially positioned, and the cable-side connector 31 is pushed into the case-side connector 21 in a state where the rotational position of the second mark M2 of the cable-side connector 31 coincides with the first mark M1 of the case-side connector 21.
Thereby, the plurality of pin contacts 22 of the case-side connector 21 shown in fig. 2 are inserted into the plurality of socket contacts 32 of the cable-side connector 31 shown in fig. 4, and the cylindrical body 24 of the case-side connector 21 is inserted into the annular gap between the insulator 33 and the cylindrical body 34 of the cable-side connector 31, the cylindrical body 34 of the cable-side connector 31 is inserted into the annular gap between the cylindrical body 24 and the housing 25 of the case-side connector 21, and the cylindrical portion 26 of the housing 25 of the case-side connector 21 is inserted into the annular gap between the cylindrical body 34 and the coupling nut 35 of the cable-side connector 31.
Since the rotational position of the second mark M2 of the cable-side connector 31 coincides with the first mark M1 of the case-side connector 21, the pair of protrusions 36 formed on the inner peripheral surface of the coupling nut 35 of the cable-side connector 31 are inserted into the guide portions 27A of the pair of groove portions 27 formed on the outer peripheral surface of the cylindrical portion 26 of the housing 25 of the case-side connector 21 shown in fig. 3 by the cylindrical portion 26 of the housing 25 of the case-side connector 21 being inserted into the annular gap between the cylindrical body 34 and the coupling nut 35 of the cable-side connector 31.
In this state, if the cable-side connector 31 is pushed into the case-side connector 21, the pair of projections 36 of the coupling nut 35 of the cable-side connector 31 come into contact with the side edges of the guide portions 27A of the pair of groove portions 27 of the case 25 of the case-side connector 21, and the coupling nut 35 moves to the rear portion of the case 25 in the guide portions 27A while overcoming the elastic force received from an unillustrated elastic member.
Further, if the pair of projections 36 of the coupling nut 35 reaches the portion of the pair of groove portions 27 where the groove width in the circumferential direction of the guide portion 27A is the narrowest, the coupling nut 35 rotates due to the elastic force received from an unillustrated elastic member, and the pair of projections 36 are fitted into the fixing portions 27B of the pair of groove portions 27. Thereby, the pair of projections 36 of the coupling nut 35 cannot move in the direction of the central axis C1 with respect to the housing 25 of the case-side connector 21.
Thus, by press-fitting the cable-side connector 31 into the case-side connector 21, as shown in fig. 7, the cable-side connector 31 is fitted into the case-side connector 21, and the fitted state of the cable-side connector 31 with respect to the case-side connector 21 is locked.
In order to detach the cable-side connector 31 from the case-side connector 21, the pair of projections 36 of the connection nut 35 may be detached from the fixing portions 27B of the pair of groove portions 27 of the housing 25 by rotating the connection nut 35 of the cable-side connector 31 against an elastic force received from an unillustrated elastic member, and the cable-side connector 31 may be pulled out from the case-side connector 21 in this state.
By fitting the cable-side connector 31 to the case-side connector 21, connecting the cable 41 to the case 12, grasping the teaching device 11 with both hands of the operator, and operating the plurality of operation sections 14 while observing the display 13, it is possible to teach operations of a controller such as a robot, a machine tool, or an actuator, not shown, connected to the teaching device 11 via the cable 41. In the case where the display 13 is configured by a display with a touch panel, teaching of an operation can be performed by operating the display with a touch panel and the plurality of operation units 14.
At this time, for example, the cable 41 connected via the connector assembly constituted by the case-side connector 21 and the cable-side connector 31 is drawn obliquely downward of the case 12, and the teaching device 11 gripped by both hands of the operator is oriented in a posture in which the plane P2 on the-Y direction side of the case 12 is directed downward.
Therefore, if the teaching device 11 is erroneously separated from the hand of the operator and dropped downward during the teaching task, the teaching device 11 collides with the floor or the ground while keeping the plane P2 on the-Y direction side of the housing 12 directed downward, and a dropping impact force is applied to the housing-side connector 21 obliquely arranged at the corner of the housing 12, which is the intersection of the planes P2 and P3 of the housing 12, and the cable-side connector 31 fitted to the housing-side connector 21. In particular, a large impact force is applied in a direction parallel to a plane P1 orthogonal to both planes P2 and P3 of the housing 12 on which the housing-side connector 21 is arranged, that is, in a direction along the XY plane.
However, the pair of groove portions 27 of the case 25 are arranged in the Z direction, which is a direction perpendicular to the plane P1 that forms both the two planes P2 and P3 that form the corners of the housing 12 as the arrangement position of the housing-side connector 21, with respect to the central axis C1. Therefore, in the cylindrical portion 26 of the case 25, there is no thin portion whose thickness is reduced by the formation of the groove portion 27 in the direction parallel to the plane P1 with respect to the central axis C1, and only a thick portion having a predetermined thickness is present, and even when a large impact force is received by dropping, the case 25 can be prevented from being damaged. As a result, the reliability of the connection between the cable 41 and the teaching device 11 by the connector assembly a including the case-side connector 21 and the cable-side connector 31 can be improved.
As described above, in the teaching apparatus 11 according to the embodiment, the housing-side connector 21 of the so-called one-touch lock type, which can easily perform fitting with the cable-side connector 31 and locking of the fitted state, is disposed at a corner of the housing 12 in an inclined manner, and durability against a drop impact can be improved.
In the above embodiment, the housing 25 of the case-side connector 21 and the connection nut 35 of the cable-side connector 31 are formed of a resin material, but may be formed of a metal material.
However, by arranging the case-side connector 21 at the corner of the case 12 so that the groove portion 27 of the case 25 and the projection 36 of the coupling nut 35 are arranged in a direction other than the direction parallel to the plane P1 of both the two planes P2 and P3 orthogonal to the intersection of the case 12 with respect to the central axis C1 when the cable-side connector 31 is fitted, even if the case-side connector 21 and the cable-side connector 31 are formed of a resin material, the impact of falling can be sufficiently received. Therefore, by forming the case-side connector 21 and the cable-side connector 31 from a resin material, the weight of the connector assembly a and the teaching device 11 can be reduced.
In the above embodiment, the case-side connector 21 is a receptacle connector having the housing 25 and the cable-side connector 31 is a plug connector having the coupling nut 35, but conversely, the case-side connector 21 may be a plug connector having the coupling nut and the cable-side connector 31 may be a receptacle connector having the housing.
In this case, if the groove formed in the housing of the cable-side connector 31 and the projection formed in the connection nut of the case-side connector 21 are arranged in a direction other than a direction parallel to the plane P1 of both the two planes P2 and P3 orthogonal to the intersection of the case 11 with respect to the central axis C1 of the case-side connector 21 when the case-side connector 21 is fitted to the cable-side connector 31, the case with a connector and the teaching apparatus 11 having excellent durability against impact of falling can be realized.
In the above embodiment, the pair of groove portions 27 is formed in the housing 25 of the case-side connector 21, and the pair of projections 36 is formed in the coupling nut 35 of the cable-side connector 31, but the number of the groove portions 27 and the projections 36 is not limited to two. Any of the groove portions 27 and the projections 36 may be provided with three or more groove portions 27 and three or more projections 36 as long as they are arranged in a direction other than a direction parallel to the plane P1 of both the two planes P2 and P3 orthogonal to the intersection of the housing 11 with respect to the central axis C1 of the housing-side connector 21 when the housing-side connector 21 is fitted to the cable-side connector 31.
The present invention is not limited to the teaching device, and can be applied to various devices having a housing with a connector in which a so-called one-touch lock type connector is obliquely arranged at a corner of the housing.
